Due to the many good reviews, I probably had too high expectations of the drama... unfortunately it didn't really grab me. Unfortunately, I actually found it rather boring most of the time. A lot of things were dragged out for so long. The many scenes of them just being silent and staring into space were just too common. Towards the end I skipped most of it when there was no talking. Gang Doo and his relationships with the other characters are really great and overall I thought the acting was okay, but the female lead was somehow too... flat and pale for me. I would have liked her to really stand up for herself. I was hardly interested in any of the characters and there are so many storylines for the different characters. It was really a struggle to get through all the episodes when you don't care about most of them. But I'm also not someone who likes to drop series... I certainly can't share the great enthusiasm, even though there are a lot of nice quotes and I can understand why people are so enthusiastic, but the series just wasn't for me.
